iKendall, State of Illinois, have invented a new and useful Road-Grading Machine, of which the following is aspecification.

This invention relates to road grading machines, one of its objects being to pro vide -a machine of this character so constructed as to prevent dirt from piling up in front of the scraping blade and interfering with the operation of the machine, it having been found that this objectionable result ,often occurs in connection with road graders such as heretoforeconstructed and particularly where sod is gathered up-by the scraper. I

A further object is to provide an improved connection between the scraping blade and the wheel supported structure whereby said blade can be readily shifted angularly with out lost motion and without causing any of -the parts to bind to an undesirable extent,

A further object isto provide improved means for adjusting the blade angular-1y and to provide additional means for holding the subsequent to the adjustment of the blade,

A further object is to provide novel means for shifting the beam laterally relative to the rear supporting wheels.

Another object, is to provide improved means for raising and lowering the blade Tith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and. in the details of constructio 1; hereinafter de scribed and claimed, it being understood that changes in 'theprecise embodiment of the invention herein disclosed, c'anbe made within the scope of what is claimed, without departing from the spirit of the invention.

PHOTOGRAPHIC PLATE AND HOLDER.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed April 16, 1913. Serial No. 761,446.

To all whom it may concern:

Be it known that I, GEORGE N. Pirnii, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and .State of Ohio, have invented a certain new and useful Improvement in Photographic Plates and Holders, of which the following is a full, 'clear, and exact'description.

This invention relates to a sensitized plate and holder therefor adapted particularly for use in automatic photographing machines, such as forms the subject matter of my prior application 730,198 filed November 8th, 1912.

In my application above referred to, there is disclosed an automatic photographing apparatus wherein by the manual actuation of a coin controlling slide mechanism and the closing of a suitable switch, a sensitized plate is delivered from a magazine to a camera and there receives its photographic exposure; thence the plate gravitates to a suitable support on which it is retained while it is subjected to several successive developing and finishing steps or operations which produce directly on to the plate a finished positive picture; and thence it isautomatically ejected from the apparatus.

In the apparatus forming the subject matter of my prior application above referred to, the several solutions are applied, and thence discharged from theplate in such an effective manner, that a very desirable positive picture is obtained in a remarkably short space of time; in fact, only a fraction of a minute elapsing from thetime that the slide mechanism is operated until the tinished picture is ejected from the apparatus.-

These desirable results are obtained very largely by the form of the plate and its -holder, and by the process and apparatus which I use in applying the solutions to and in discharging them from the plate. Briefly statbd, this is doneby causing the solutions to drop on to the plate while the latter is held in a horizontal position and thence by spinning the 'plate and its holder to cause the solution to be completely and effectively discharged therefrom by the action of centrifugal force.

The object of the present invention is to provide for the plate a holder which will gravitate through the machine in the manner' desired; which is proof against moisture, and, at the same time, Wlll be unaffected by the acidulated solutions; which will retain or hold a quantity of each solution when the latter is dropped onto the plate in such a manner that the entire plate will be covered and may be acted upon by the sol ution; and which will enable a solution to be cleanly and entirely thrown from the plate before the next solution is applied. These and other objects are attained by my invention which may be briefly summarized as consisting in certain novel details of construction and combinations and arrangements of parts which will be described in the specification and set forth in the appended claims.

In the drawing wherein I have shown the preferred form of my invention, Figure l is a face or plan view of the plate and holder, and Fig. 2 is an enlarged transverse sectional view.

In the drawing 10, represents the photographic plate which is formed of thin paper suitably sensitized on its upper face and is Circular. This plate is held in a holder or mount which, in this case, consists of two principal parts including first a circular backing or base plate or disk 11, preferably formed of card board and an annular retaining member 12, which is preferably formed of card board or paper stock, and is water proofed. The diameter of the inner opening of this member 12 is somewhat less than the diameter of the plate 10. and the outside diameter of the member 12 is the same as the diameter of the base plate or disk 11. As shown in Fig. 2, the inner part of the member 1.2 bears upon the edge por tion of the plate and the outer part bears upon the outer part of the base plate or disk ll. The inner and outer portions of the member 12 or the portions which engage respectively the plate 10 and the disk 11 are provided with water proof adhesive so that saidjnirts are fastened together securely at all points or completely around the inner and outer peripheries.

Between the inner and outer edges of the member 12, is an outstandingannular embossinent 12 which leaves on the inside of the embossment a depression .of such a depth that a suitable amount of solution can be retained in the holder to completely cover the face of the plate 10. Inother words, this embossment forms the holder into a tray or receptacle. It will be observed also connected. Thus the blade can be caused. to

grade an inclined surface. F or the purpose of adjusting the blade angularly in a horizontal plane, the pin 59 is disengaged from the half circle and the draw bar is disengaged from the beam 1. -The blade 24 can then be swung about the ball 22 as a pivot until it has been brought to a desired angle after which pin 59 is reinsertedinto the half circle and the bar 30 is readjusted a bracket secured to and arranged under the beam, said bracket having a tongue provided into-engagement with beam 1 and with'the socket 27 adjacent the front end of the scraping blade.

The entire blade can be quickly elevated by means, of the rack bar 64; and gear 67, as hereinbefore described,

-As the beam l'is arched directly in front of the scraper blade, it will be seen that there is no danger of dirt and sod becoming lodged under the beam and interfering with" the proper operation of the'scraper.

V Vhat is claimed is "side thereof, a scraper bladeextending un- 'der the beam, said blade being movably con nected to 'the beam, a draw bar, stems extending laterally from one end thereof, one stem being provided-for, and adapted to she either end.
